STUDY QUESTION: Is it feasible to undertake a randomised controlled trial to establish whether surgical removal of endometrioma or not, improves live birth rates from IVF? SUMMARY ANSWER: A randomised controlled trial (RCT) comparing surge…

BACKGROUND: The reproductive impact of adenomyosis and endometriosis is widely researched but the extent of these impacts remains elusive. It has been demonstrated that endometriosis, in particular, is known to result in subfertility but en…

BACKGROUND: Polycystic ovarian syndrome (PCOS) occurs in 4% to 7% of all women of reproductive age and 50% of women presenting with subfertility. Subfertility affects 15% to 20% of couples trying to conceive. A significant proportion of the…

Better imaging techniques will result in more women who are undergoing in vitro fertilization (IVF) being diagnosed with adenomyosis. Preliminary data suggest that adenomyosis may have implications for the outcome of IVF. However, available…

BACKGROUND: Gonadotropins are the most commonly used medications for controlled ovarian stimulation in in vitro fertilisation (IVF). However, they are expensive and invasive, and are associated with the risk of ovarian hyperstimulation synd…
